Ultrafine Bubbles (UFB) Alleviate Toxicity of Fluxametamide‐Based Insecticides to Nontarget Freshwater Species, Daphnia magna

Environmental Quality Management, Volume 35, Issue 1, Fall 2025.
ABSTRACT Pesticide contamination in freshwater ecosystems poses a significant threat to water quality and aquatic life, potentially disrupting entire food webs. Fluxametamide (FMT), a novel insecticide regarded as safe for nontarget species, has not been extensively studied in aquatic environments, raising concerns about its potential toxicity to ...

Planthopper protein Nlsp5 is essential for salivary sheath formation and acts as a HAMP inducing plant resistance to insects

Plant Biotechnology Journal, Volume 23, Issue 9, Page 4076-4091, September 2025.
Summary During herbivore feeding, plants can recognize herbivore‐associated molecular patterns (HAMPs) present in saliva and trigger pattern‐triggered immunity (PTI). Piercing‐sucking insects secrete gel saliva, forming salivary sheaths that aid in feeding. However, the role of proteins within these salivary sheaths in modulating plant defences remains

Validation of Reference Genes for Quantitative Real-Time PCR in Laodelphax striatellus

Journal of Integrative Agriculture, 2014
The normalization of quantitative real-time PCR (qPCR) is important to obtain accurate gene expression data, and the most common method for qPCR normalization is to use reference genes. However, reference genes can be regulated under different conditions.

Bifenthrin resistance in Dalbulus maidis (Hemiptera: Cicadellidae): inheritance, cross‐resistance, and stability

Pest Management Science, Volume 81, Issue 8, Page 4810-4820, August 2025.
Resistance of Dalbulus maidis to bifenthrin was autosomal, incompletely dominant, and polygenic. Additionally, this resistance was unstable in the absence of selection pressure. Abstract BACKGROUND Pyrethroid insecticides have been a primary strategy for managing Dalbulus maidis (Hemiptera: Cicadellidae) in Brazil. Howeve, failures in the control of D.

Knockdown of timeless Disrupts the Circadian Behavioral Rhythms in Laodelphax striatellus (Hemiptera: Delphacidae)

Environmental Entomology, 2018
Most living organisms developed the innate clock system to anticipate daily environmental changes and to enhance their chances of survival. timeless (tim) is a canonical clock gene. It has been extensively studied in Drosophila melanogaster (Diptera: Drosophilidae) as a key component of the endogenous circadian clock, but its role is largely unknown in

The Effect of Landscape Composition on the Abundance of Laodelphax striatellus Fallén in Fragmented Agricultural Landscapes

Land, 2016
The spatial distribution of crop and non-crop habitats over segmented agricultural landscapes could be used as a means to reduce insect pest populations.

Construction of cytomegalovirus promoter‐driven gene expression system in Laodelphax striatellus

Insect Science
AbstractThe small brown planthopper (SBPH, Laodelphax striatellus) is a significant rice pest, responsible for transmitting rice stripe virus (RSV) in a persistent and propagative manner. RSV is one of the most detrimental rice viruses, causing rice stripe disease, which results in considerable loss of rice grain yield.

Rice Black-streaked Dwarf Virus Preparation and Infection on Rice

Bio-Protocol, 2017
Rice black-streaked dwarf virus (RBSDV), a member of genus Fijivirus in the family Reoviridae, infects rice, maize, barley and wheat, and can seriously affect crop yields. RBSDV is transmitted by the small brown planthopper (Laodelphax striatellus, SBPH)

Insect-transmitted plant virus balances its vertical transmission through regulating Rab1-mediated receptor localization

Cell Reports
Summary: Rice stripe virus (RSV) establishes infection in the ovaries of its vector insect, Laodelphax striatellus. We demonstrate that RSV infection delays ovarian maturation by inhibiting membrane localization of the vitellogenin receptor (VgR ...

Diapause Induction and Termination in the Small Brown Planthopper, Laodelphax striatellus (Hemiptera: Delphacidae)

PLoS ONE, 2014
The small brown planthopper, Laodelphax striatellus (Fallén) enters the photoperiodic induction of diapause as 3rd or 4th instar nymphs. The photoperiodic response curves in this planthopper showed a typical long-day response type with a critical daylength of approximately 11 h at 25 °C, 12 h at 22 and 20 °C and 12.5 h at 18 °C, and diapause induction ...
